Answer:
The probability that the coin landed heads is 65.3%.
Step-by-step explanation:
Given : Urn A has 5 white and 17 red balls. Urn B has 9 white and 12 red balls. We flip a fair coin. If the outcome is heads, then a ball from urn A is selected, whereas if the outcome is tails, then a ball from urn B is selected. Suppose that a white ball is selected.
To find : What is the probability that the coin landed heads ?
Solution :
Let the event A be the ball taken from Urn A (5 white and 17 red balls)
Let B=A'- the ball taken from urn B(9 white and 12 red balls)
Let W be event that a white ball is selected.
An urn is chosen based on a toss of a fair coin.
P(A) = coin landed on heads =
P(B) = coin landed on tails =
and
Using Bayes formula,
Therefore, the probability that the coin landed heads is 65.3%.
Step-by-step explanation:
Given the average of 8 numbers = 56.
Then the Total sum of 8 numbers = 56 * 8
= 448.
Sum of 1st three numbers = 49 + 57 + 72
= 178.
So, the total = 448 - 178
= 270.
Average of the other 5 numbers = 270/5
= 54.
Verification:
178 + 270 = 448/8
= 56.

Answer:
120º
Step-by-step explanation:
First we need to know the fraction of the area of ORT to the area of the circle.
Fraction = 18π/54π = 1/3
We know that a circle is 360º, and sector ORT is xº. The fraction of the sector of ORT to the circle must also be equal to 1/3.
x/360 = 1/3
3x = 360
x = 120º
